1. Customizable range between 10SLM and 500SLM

2. SLM: Standard liters per minute. Standard conditions: 0 ° C and 1 atmosphere

3. In addition, the two-way airflow test can be customized, and the analog output is correspondingly changed. F(min)—F(max) corresponds to 1-5V output, and 0 flow corresponds to 3V;

4. Includes temperature drift and linearity error

Linear Output

1. The unidirectional airflow mode: (calculation formula)

Flow = [(VOUT -1 V) / 4 V] × full scale flow

For example: S4103V has a full-scale flow of 200 SLM. When the output voltage is read at 2.5V,

the instantaneous flow rate is [(2.5V-1V) / 4V × 200 SLM] = 75 SLM

2. Two-way airflow mode: (calculation formula)

Forward flow = [(VOUT -3 V)/2 V] × full scale flow

Reverse flow = [(3 V- VOUT)/2 V] × full scale flow

Shell Size

Note 1: The connector can be matched with a connecting line according to customer requirements.
